Using a Powered USB Hub for a 30ft Webcam Setup: Will it Work?

I'm trying to set up a webcam that needs to be placed about 30 feet away from my PC for volunteer work. My budget is tight as I'm trying to gather various equipment for the task. I have two 16-foot USB cables, and while one works fine on its own, connecting both doesn't seem to work. If I use a powered USB hub between the two cables, do you think that would successfully power the webcam?

Actually, what you really need is a USB over Ethernet solution. It can be a bit pricier, but it allows for USB connections over greater distances using Ethernet cables. Perfect for your needs!

USB cables have maximum length limits, and powering devices over long distances can be tricky. A powered hub might help, but it’s not primarily designed for this use case. Is there a way you could get the PC closer?

You're pushing the limits of USB here! I suggest opting for a PoE webcam along with a PoE injector or switch. This combo should keep your costs under $100, and it works like a charm!

SmartDecisionMaker: Agreed! Unless your goal is security, a PoE webcam would indeed be a more sensible approach.

Have you considered using a Wi-Fi webcam instead? They can be quite affordable—something around $25 might work out cheaper for your setup.

You're right about power and data transmission issues over long distances. While a powered hub could potentially help, I recommend looking into active USB extension cables as they can handle longer distances more effectively. They might just do the trick!
